of the conductor or wire 13 which extends through the trolley pole and connects with the motor equipment.

The side bearing arms 3 of the harp support a transverse double cone axle 15 having the separate opposite conical portions 16, 16, upon which are rotatably fitted the. self-adjusting bearing bushings 17. These bearing bushings 17 are provided with interior taper openings 18 registering with the conical portions 16, and said bearing bushings also register and slidably engage with the side bearing openings 19 provided in the opposite sides of the trolley wheel 20'. The said bushings are suitably interlocked with the wheel so as to rotate therewith and at the same time be capable of sliding therein. This wheel is preferably of integral formation and is provided with an interior lubricant chamber 21 with which communicates suitably arranged plugged filling openings 21 Flat take-up springs 22 are secured fast at their lower ends, as at 23, to the inner side and lower end portions of the bearing arms 3, and the free ends of said springs are arranged to bear and exert an inward pressure against the outer sides of the bearing cones 17 To supplement this action, there is employed an auxiliary coiled pressure spring 24 seated in a spring socket 25 formed in the inner side of a detachable cap plate section 26 held in the outer end of one of the side bearing arms 3 by means of a retaining screw 27.

I claim:

In a device of the character described, the support carrying a double cone axle, a wheel having an interior lubricant chamber and side bearing openings, self-adjusting bearing bushings rotatable with the wheels, said bushings engaging over the conical portions of the axle and fitting in said bearing openings, fiat take-up springs arranged to exert an inward stress on said cones, and an auxiliary coiled pressure spring arranged at one side of one of the flat springs.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
